A lot of people search for "glyphosate-free collagen," but here is the honest truth: no food or supplement can promise to be perfectly free of a molecule. What a trustworthy brand can do is test the finished product and prove there is no detectable glyphosate residue down to a strict limit. That standard has a name, Glyphosate Residue-Free, and it is exactly what Yonder carries: our collagen peptides are certified Glyphosate Residue-Free by The Detox Project. Here is what that certification really tests for, and how to tell a genuinely clean collagen from one that just looks clean on the label.
See our full Glyphosate Residue-Free certification page for the Detox Project seal, lab testing details, and how to verify our certification.
What does "glyphosate-free" collagen really mean?
"Glyphosate-free" is the phrase shoppers type, but it is not a phrase a careful brand should claim, because you cannot prove a total absence of something down to zero. What you can do is send the finished product to an accredited laboratory and verify there is no glyphosate residue down to a very low detection limit. When a product passes that test on an ongoing basis, it earns a real, third-party label: Glyphosate Residue-Free.
So the accurate question is not "is it glyphosate-free," it is "has it been tested and certified Glyphosate Residue-Free." One is a marketing word. The other is a lab result. That difference is the whole point of this article.
How does glyphosate end up in collagen?
Glyphosate is the most widely used agricultural herbicide in the world. Collagen peptides are made from the hides and connective tissue of cattle, so the cleanliness of the finished powder traces back to how those animals were raised and fed.
When cattle are finished on grain, that grain is often grown with glyphosate, and in some cases glyphosate is used as a pre-harvest drying agent. Residues from feed can carry through into the animal and, ultimately, into collagen made from it. This is why grass-fed alone is not enough. An animal can be grass-fed for most of its life and still be grain-finished at the end. What you want is grass-fed and grass-finished, pasture-raised cattle, so there is no grain-feed pathway to begin with.
In other words, clean collagen starts on the pasture, long before anything reaches a tub.
Why isn't most collagen tested for glyphosate?
Two reasons. First, glyphosate testing is not required, so most brands simply do not do it. Second, testing to a meaningful detection limit costs money and has to be repeated, so it is easy to skip.
The result is a market full of collagen that has never been checked for the most common herbicide on earth. For a product you may stir into your coffee every single morning, that gap matters. Daily habits deserve daily-habit-level scrutiny.
What does Glyphosate Residue-Free certification actually test for?
This is where it gets specific, and where most "clean" claims fall apart. The Glyphosate Residue-Free certification, administered by The Detox Project, tests the finished product (not just the ingredients) at an ISO 17025 accredited laboratory using LC-MS/MS, one of the most sensitive testing methods available.
It checks for two things, not one:
- Glyphosate itself, and
- AMPA, glyphosate's primary breakdown product. A product can read low on glyphosate but still show its metabolite, so a serious test screens for both.
To qualify, the finished product has to show no residue down to roughly 10 parts per billion (0.01 ppm), and certified products are re-tested on an ongoing basis. Yonder verifies its finished product through Light Labs, an ISO 17025 accredited laboratory, to exactly this standard.
That is a meaningfully higher bar than "we believe our product is clean." It is an outside lab, a sensitive method, two analytes, a strict limit, and repeat testing. Until recently only a small handful of collagen brands carried this certification at all, which is part of why so few clean options surface when you go looking. Yonder is one of the brands that does.
Is bone broth the same as collagen peptides?
Bone broth is wonderful, and homemade broth has real nutritional value. But as a daily collagen source it has two practical limitations.
First, the amount of collagen in bone broth varies batch to batch, so it is hard to know how much you are getting on any given day. Isolated, third-party-tested collagen peptides give you a consistent, measured amount in every scoop. Second, broth and protein powders are rarely, if ever, certified Glyphosate Residue-Free, so you are back to the same untested-purity problem.
If your goal is a clean, reliable daily intake, hydrolyzed collagen peptides from a certified source do the job more consistently than broth alone.
What to look for in a truly clean collagen
Use this as a label-check the next time you shop:
| What to look for | Why it matters | Yonder |
|---|---|---|
| Certified Glyphosate Residue-Free by The Detox Project | Independent, lab-verified purity (glyphosate + AMPA), not a marketing word | Yes |
| Grass-fed AND grass-finished, pasture-raised | Closes the grain-feed residue pathway | Yes |
| Single ingredient (just collagen peptides) | No fillers, sweeteners, flavors, or additives | Yes |
| Third-party tested for heavy metals | Screens for other common contaminants | Yes |
| Hydrolyzed peptides | Smaller chains for easy mixing and absorption | Yes |
If a collagen checks every one of those boxes, you have found a genuinely clean one. Most do not.

Why we made Yonder this way
We did not set out to start a supplement company. We set out to find a collagen clean enough for our own families, and we could not. So we built it.
Yonder collagen is certified Glyphosate Residue-Free by The Detox Project, sourced from 100% grass-fed and grass-finished, pasture-raised cattle, made from a single ingredient, and third-party tested for purity and heavy metals. One to two scoops gives you 10 to 20g of collagen, with 9 to 18g of clean, grass-fed protein as a bonus. It is flavorless and stirs into hot or cold drinks without changing the taste, which is exactly why it is so easy to make part of a morning routine.
We lead with purity because purity is the reason Yonder exists.

What the research says about collagen peptides
Beyond purity, here is what peer-reviewed research on collagen peptides actually supports. (Studies referenced below are indexed on PubMed.)
- Skin: In a double-blind, randomized controlled trial, daily collagen peptides significantly improved skin elasticity in women compared with placebo (Proksch et al., 2014). A separate trial found a significant reduction in eye-wrinkle volume and increased procollagen and elastin in the skin (Proksch et al., 2014). Collagen peptides support skin elasticity and hydration.*
- Bone: In a 12-month randomized controlled trial in postmenopausal women, specific collagen peptides significantly increased bone mineral density at the spine and hip (Koenig et al., 2018). Collagen supports bone health, particularly for women in midlife.*
- Joints: Randomized controlled trials report improvements in joint comfort and function with collagen peptides (Genc et al., 2025). Collagen supports joint comfort during normal daily activity.*
- Nails: Daily collagen peptides increased nail growth rate and reduced brittleness in a clinical study (Hexsel et al., 2017). Collagen supports nail strength and helps reduce brittleness.*
- Muscle composition: Combined with regular resistance activity, collagen peptides increased fat-free mass in a randomized controlled trial (Zdzieblik et al., 2021). Collagen supports muscle composition when paired with activity.*
The takeaway: collagen peptides are well-studied for skin, bone, joint, nail, and muscle support. Choosing a clean, certified one means you get those benefits without an untested daily dose of herbicide along with them.
Frequently asked questions
Is "glyphosate-free collagen" a real thing?
Not exactly. No supplement can promise to be perfectly free of a molecule. The real, testable standard is Glyphosate Residue-Free, meaning the finished product is lab-tested for glyphosate and its metabolite AMPA with no residue detected down to a strict limit. Yonder is certified Glyphosate Residue-Free by The Detox Project.
Is all grass-fed collagen Glyphosate Residue-Free?
No. Grass-fed describes most of an animal's life, but many cattle are still grain-finished, which reintroduces a glyphosate pathway. Look for grass-fed and grass-finished, plus the actual certification.
How much collagen should I take per day?
Most research uses about 10 to 20g daily. With Yonder, that is one to two scoops.
Can I put it in hot coffee?
Yes. Yonder is flavorless and dissolves in hot or cold liquids without changing the taste. Stir it into your morning coffee, tea, or smoothie.
